...FLASH FLOOD WATCH FOR RECENT BURN AREAS ACROSS SOUTHWESTERN
CALIFORNIA...
.A large and powerful storm system across the Eastern Pacific is
expected to approach the West Coast through Friday. A subtropical
fetch of moisture well ahead of the system is expected to bring
periods of moderate to heavy rain to portions of Southwest
California as early as Tuesday afternoon and continuing through
late Thursday or early Friday. The most widespread moderate to
heavy rain currently looks to be focused along and ahead of a cold
front pushing through the region Wednesday night into Thursday.
Flash flooding and mud and debris flows are likely in and around
recent burn areas in the watch area. There is the potential that
the Flash Flood Watch will need to be expanded to include areas
outside of recent burn areas during the peak of the storm system
Wednesday night into Thursday. Rain will likely come to an end
behind the cold front sometime late Thursday into early Friday.
Storm total rainfall is expected to range from 2 to 5 inches
across coastal and valley areas, with 5 to locally 10 inches
across the foothills and coastal slopes.
